New performance standards for demineralization set by Recoflo{reg_sign} technology
- Eco-Tec Inc., Pickering, Ontario (Canada)
The design of the ion exchange equipment used in water treatment for boiler water makeup hasn`t changed much in the last 30 years--at least in North America. The Recoflo process is a clear break from that tradition. Application of the technology to boiler water treatment allows users to realize a number of significant advantages over conventionally designed, concurrently regenerated ion exchange systems. Demineralization systems using the Recoflo process take up much less space, make more efficient use of regenerant chemicals, produce less waste and are fully automated, minimizing the amount of operator attention required. Using this process, two bed ion exchangers produce demineralized water qualities that more conventionally designed systems need mixed bed polishers to produce. The Recoflo process uses shallow (typically 6 inches deep), fully packed beds of fine mesh ion exchange resin. The ion exchange beds are operated at high flow rates and are regenerated counter-currently. Total cycle times in water treatment applications are typically less than 30 minutes. The paper will describe the Recoflo demineralization process, and brief case histories of its use in a number of power plants and cogeneration facilities will be presented.
